hosts of the green aphis and Chermes affecting conifers. Insects 

 injurious to greenhouse and garden plants and stored products will be 

 studied with a view to determining their life-histories and methods of 

 control. Observations on, and introduction of parasites of the gipsy 

 moth [Lymaniria dispar], brown-tail moth [Euproctis chnjsorrhoea], 

 tent caterpillars [Makicosonia], etc., will be continued.

 Scotia. — Dominion of Canada Dept. Agric, Entom. Branch, 

 Ottawa, Circ. no. 7, 1916, 11 pp. [Received 14th June 1916.] 

 This paper records the experimental data obtained between 1911 

 and 1914 inclusive as to the effect of spraying on certain varieties of 

 apples. The results show a marked increase in the quantity of market- 

 able fruit, a general improvement in quality and a rise in profits, 

 A spraying calendar for apple orchards in Nova Scotia is given.

Biosteres rhagoletii, Richmond. — Canadian Entomologist, London, 



Ont., xlviii, no. 5, May, 1916, p. 168. 



An account is given of the method of oviposition of Biosteres 



rhagoletis. This parasite probably causes high mortahty among the 



larvae and pupae of the apple maggot [Rhagoletis pomonella] in Nova 



Scotia.

Draeadacephala mollipes. Say, was abundant throughout the season, 

 especially in northern Arkansas, where maize was considerably injured 

 during early summer. Eggs were apparently only deposited on grain, 

 grasses and grass-like plants. Diedrocephala versuta, Say, became 

 numerous in late summer, attacking cow-peas, lucerne, and ornamental 

 plants in Missouri. D. coccinea, Say, was observed on weeds and 

 ornamental trees and shrubs, including American holly and magnoha. 

 Phlepsius irroratus, Say, attacked lucerne and clover throughout the 

 central valley as well as various grains during the spring months. 

 The nymphs aud adults caused injury by feeding on the stems and were 

 active during both the day and night. Agallia sanguinolenta, Prov. 

 (clover leaf -hopper), together with Empoasca mali, caused some damage 

 to lucerne and red clover in south-east Missouri in the early summer, 

 but was easily captured by the use of a hopperdozer. This species 

 was able to feed actively during cold days in winter. E. mali, Le B., 

 attacking lucerne, clover, and other crops, was the most injurious 

 species found during the year. In southern lUinois, there were 

 probably at least six generations during the year. This species, as 

 well as the preceding, may be important in spreading yellow and brown 

 leaf spot of lucerne, due to Pseudopeziza medicaginis and Coletotrichum 

 trifolium respectively. Other Jassids common during the year were : — • 

 Pediopsis viridis. Fitch ; Agallia constricta, Say ; Cicadula 6-notata, 

 Fall. ; Deliocephalus inimicus. Say ; D. nigrofrons, Forbes ; Athysanus 

 exitiosus, Uhl. ; A. bicolor, van D. ; Platymetopius frontalis, van D. ; 

 Eutettix seininitda. Say ; Typhlocyba comes, Say.
